Experience With Linear Tracking Turntables

@lewm interesting ur experience with a B and O cartridge. I understand from

speaking to the Classic HiFi writer at Hi News Tim Jarman that the cartridges were designed to be in the linear tracking B&O turntables and turntables. As such the styli was very small and it was properly thought out as a whole system. I have a 4002 awaiting a rebuild. B&O have some incredible designers who apply their art and knowledge more for a luxury than audiophile market but dismiss their savour faire at your peril. Their top end speakers that manipulate sound around a room are exceptionally clever and sound pretty good too. 
@mijostyn speaks about the problem with lateral compliance which I’m sure is right as it makes sense - but it puzzles me that Kuzma released a silly money arm which is unusually heavy and apparently it throws the whole compliance thing out of the window - that being said the weight (being a pivoted arm) has the weight in all directions.

@mijostyn and @dover 

I get the mass is mass - likewise I also get the issue with reviewers - many a culprit there - too many to mention - a lot of Emperors New Clothes.

The Derrenger (at least i think that's the name) does a very sophisticated 'active' lateral movement - that makes sense.

The old B and O has a hybrid mechanical lateral insofar as it pivots and upon getting to a point shuffles along actively. remember - it had a very light arm and was properly thought out - in fact i liked thee engineering approach of thinking out of the box - shame there is no affordable modern alternative that can be fitted to other decks.
